As each a 35 yr esthetician and a skincare product formulator skilled in beauty chemistry, what I do know for certain is there are a number of false hopes being bought in regards to the newest and biggest “miracle” elements – and it’s really easy to fall into the advertising and marketing hype.
I’ve seen a number of elements come and go and are available again once more (whats up hyaluronic acid!) however the one which has remained regular is vitamin C. Why? As a result of it really works for night out pigmentation by interrupting the over-production of melanin which causes hyperpigmentation. Plus, working with faces hands-on, I’ve seen unimaginable enhancements in my shoppers pores and skin, giving their pores and skin the brightness that they need.
However…not all vitamin C elements and what’s now thought of “the gold commonplace” is Tetrahexyldecyl Ascorabate, often known as THD Ascorbate.
So, let’s do a deep dive into this ingredient, lets?
What’s THD Ascorbate?
THD, or Tetrahexyldecyl Ascorbate, is an inactive type of vitamin C. What makes THD Ascorbate so uniquely completely different from different types of vitamin C is that it’s an oil-soluble ester versus being water-soluble. When it’s oil-soluble, it means it received’t begin to react and convert into L-ascorbic acid till it hits the oils in your pores and skin, making it probably the most secure in comparison with different types of vitamin C. Plus, because it’s solubilized by oil as a substitute of water, it doesn’t require a low pH just like the water-soluble variations do.
Why Select THD Ascorbate Over Different Varieties of Vitamin C For My Face?
Have you ever ever gotten a stinging sensation from vitamin C merchandise with Ascorbic Acid, Sodium Ascorbyl Phosphate and Ascorbyl Methylsilanol Pectinate? Yep, that is a sign of their low pH together with probably the state of your pores and skin’s barrier. Whereas stinging from vitamin C with a low pH is par for the course, (learn extra about stinging from skincare merchandise), that doesn’t imply your pores and skin appreciates the every day “no ache, no acquire” assault that it will get uncovered to within the quest for brighter pores and skin. Your pores and skin’s pH resides round 5.0 and most of the water-soluble acids could be a pH of 4.0 and even decrease in order that’s the place the “ouch issue” comes from.
Identical to train, if you wish to obtain outcomes to your physique and general well being and longevity, you DO have to create some discomfort. However for the pores and skin, I like to depart these for retinol, prescription retinoids, at-home peels, my 7-day pores and skin problem {and professional} therapies like micro needling, dermaplaning, lasers (like the Moxi laser I had completed by myself pores and skin) and chemical peels.
In case your aim is to create a smoother, even-toned texture with much less seen pores, there can be unwanted effects that may compromise the pores and skin barrier and trigger irritation, however placing your pores and skin in a state of elevated sensitivity each single morning with the usage of a low pH vitamin C serum? Nope. I’m completely not a fan of that.
(Should you really feel like your barrier is broken, right here’s find out how to repair it.)
How Efficient is THD Ascorbate for Decreasing Brown Spots and Hyperpigmentation?
I used to be launched to Tetrahexyldecyl Ascorbate again in 2004 whereas searching for higher options for my shoppers combating hyperpigmentation from solar, hormones, and breakouts. Initially, I bought a 2% Hydroquinone product to focus on pigmentation which continues to be recognized to be very efficient, however throughout a beauty chemistry class at UCLA, I realized about THD’s promising results on melanin manufacturing. Apart from it not being irritating, what stood out was its stability—it was efficient right down to the final drop, guaranteeing you may get probably the most out of their funding.
This sparked my journey with THD, and inside two years, I developed a vitamin C serum utilizing this ingredient. The outcomes throughout testing had been unimaginable, and after I launched it and really helpful it to shoppers, over the course of weeks and months their solar spots, brown spots and marks from breakouts improved a lot quicker. I phased out the hydroquinone serum in favor of utilizing THD Ascorbate, which proved to me it was far simpler for pores and skin brightening.
What Proportion of THD Ascorbate Is Efficient?
It’s much less about wanting on the ingredient listing (generally known as the INCI listing) and extra about the kind of product that makes use of it. As a result of THD Ascorbate requires time to penetrate the pores and skin, it’s finest utilized in leave-on merchandise. I don’t advocate it in merchandise that rinse off the pores and skin as a result of there merely isn’t any time for the THD to get to work. Additionally, THD requires a lot decrease use ranges than ascorbic acid, because of its supreme capacity to penetrate into the pores and skin. Oftentimes customers wish to see larger percentages of elements, however extra shouldn’t be all the time extra! Pores and skin doesn’t want as a lot THD as ascorbic acid to reap its advantages. For instance, there’s a examine exhibiting the collagen-boosting results of THD at simply 0.1%. For pores and skin brightening, there are advantages seen as little as 0.5%.

Is There Scientific Analysis Proving How THD Can Assist Enhance Discoloration?
Behind the science: The first producer of THD has carried out lots of of research on the advantages of THD, which is the way it was capable of obtain quasi-drug standing in Japan and Korea at 3% and a couple of%, respectively. Sadly, these research aren’t publicly out there, however there are peer-reviewed research on the advantages of THD in pores and skin, each alone and together with different skin-lightening elements.
How Usually Ought to I Be Utilizing A Vitamin C Serum?
The advantages of utilizing a vitamin C serum is when it’s used every day as a part of your morning routine. Not solely does it assist suppress melanin manufacturing however the usage of all varieties of vitamin C helps to guard pores and skin cells from environmental harm. It scavenges free radicals, that are unstable molecules that result in pores and skin harm and speed up pores and skin getting old. Free radicals are continuously coming at us from so many various sources, together with UV gentle from the solar, ozone, smoke, and air pollution (to call a couple of). All of those are additionally liable for a pure depletion of vitamin C in our pores and skin over time, which is why supplementing with an oral antioxidant product is so necessary.
Bonus: Vitamin C helps forestall collagen breakdown and promotes more healthy collagen manufacturing. First, it helps defend the collagen you have already got by inhibiting a bunch of enzymes that break down collagen. Second, it aids in more healthy collagen manufacturing because it’s a cofactor for 2 enzymes wanted to construct and cross-link collagen.
When In My Routine Ought to I Be Utilizing A Vitamin C Serum?
At all times within the morning. Right here’s how I really like to make use of it: after I’ve cleansed and toned my pores and skin, I’ll use two pumps of Vitamin C + E Remedy and gently press it into my pores and skin with my fingertips, actually letting it set into the pores and skin for a couple of minute. This provides the powerhouse elements a second to do their factor earlier than I transfer on to my subsequent step.
After that, I end off with my favourite non pore-clogging Weightless Safety SPF 30, locking every thing in and defending my pores and skin from these pesky free radicals. It’s a easy however tremendous efficient combo that leaves my pores and skin feeling contemporary, nourished, and able to tackle the day!
Backside line about THD Ascorbate: It’s an ingredient that I worth rather a lot due to analysis and in contrast to stylish elements, this has endurance as a result of it’s a type of elements the place you’ll be able to really see the distinction which isn’t the case with a number of elements, regardless that they nonetheless are useful.
Since THD is probably the most secure type of vitamin C and now thought of to be “the gold commonplace of vitamin C”, it doesn’t want that low pH to be efficient, which is nice information for our pores and skin barrier. I hope you’ll think about making an attempt Vitamin C + E Remedy as I’ve formulated it with a pH of 5.3, making it a lot gentler on the pores and skin than most.
From my arms to your face, your pores and skin barrier will thanks!
